I have a 48 count set of Honolulu b markers. I recently got a gift card for target for my birthday and I saw they have a 36 count Oahu in store that I could get with my gift card. What is the main difference between the two other than the Oahu having chisel and fine tips, instead of brush and fine like the Honolulu B? Would I also have a lot of duplicates? TIA
